FIELD

The present disclosure relates to compositions comprising synthetic nucleic acids comprising human codons that facilitate genome editing. The present invention also relates to methods of using the compositions comprising synthetic nucleic acids for genetic engineering in human beings and other mammals BACKGROUND

Genome editing has offered a powerful tool and unprecedented opportunity to study gene functions and to fight diseases by introducing a targeted genomic sequence change at a specific locus of a living cell or organism. Zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and clustered regularly interspaced short palindromic repeats (CRISPR)-associated (Cas) nucleases are the ones that have been used successfully and efficiently by many laboratories. More recently, the RNA-guided endonucleases such as Cas9 and Cpf1 have gained more traction because of their relatively ease of manipulation. The user-friendly CRISPR-Cas9 is very efficient in making mutations via nonhomologous end joining (NHEJ) in human cancer cell lines such as 293T cells. It also can mediate homologous recombination (HR), but at a much lower efficiency (2-5%) in 293T cells and even lower in other biologically relevant cells such as human induced pluripotent stem cells (iPSCs).

Recently, it has been reported that it is feasible to achieve genome editing by using Natronobacterium gregoryi Argonaute (NgAgo) with a guide DNA oligo in human cells (Gao F, et al., (2016) Nat Biotechnol. 34(7):768-73). However, multiple labs have failed to reproduce this phenomenon claimed by Gao et al. thus far, which led to the withdrawal of this publication. Interestingly, an eye defect was observed by using an NgAgo approach in zebrafish. The phenotype was most likely caused by an NgAgo mediated gene knockdown effect, and no genetic modification was observed at the DNA level.

Argonautes use an orthogonal mechanism of immune surveillance and promise an entirely novel process for gene editing. Argonautes are a family of endonucleases that use 5′ phosphorylated short single-stranded nucleic acids as guides to cleave targets. Similar to Cas9 and Cpf1, Argonautes play key roles in gene expression repression and host defense against foreign nucleic acids. While Cas9 and Cpf1 are only naturally found in prokaryotes, members of Argonaute superfamily are reported to be present in many species (from bacteria to mammals). Although most Argonautes associate with single-stranded (ss) RNAs and play a central role in RNA silencing, some Argonautes bind ssDNAs and cleave target DNAs. It appears that DNA-guided Argonaute binding does not have a specific requirement for sequence or secondary structure. Argonautes are conserved throughout the bacterial and archaeal domains of living organisms. Their major functions are likely to be involved in DNA-guided DNA-interfering host defense systems.

An ideal gene editing tool should be able to introduce a desired base change, deletion or insertion into the genome in a precise, non-bias and error-free manner. Although CRISPR/Cas systems, originally derived from a bacterial host defense mechanism, are versatile and are currently widely used, they are error-prone and sequence-biased.

SUMMARY

Disclosed herein are several novel codon-adapted Argonaute protein variants named ANAGO that are derived from microbial Argonaute proteins capable of editing a target nucleic acid sequence within a prokaryotic cell. The DNA coding sequences of these microbial argonaute proteins, such as NgAgo, PfAgo, TtAgo and MjAgo, can be reengineered and adapted with the codons that have preferential usage in eukaryotes, such as humans to generate new synthetic DNA sequences that encodes the ANAGO that are species-specific to the eukaryotes, wherein the ANAGO conserves or retains the endonuclease activities, capable of editing a target nucleic acid sequence within a eukaryotic cell.

DETAILED DESCRIPTION

Presented herein, in some embodiments, is an ANAGO, compositions comprising an ANAGO, kits comprising an ANAGO, and uses thereof, for example, the use of the ANAGO in a homologous recombination directed genome editing in a subject, such as a eukaryote, e.g. a human being. The term “subject” refers to animals, typically mammalian animals, or plants. Any suitable mammal can be treated by a method or composition described herein. Non-limiting examples of mammals include humans, non-human primates (e.g., apes, gibbons, chimpanzees, orangutans, monkeys, macaques, and the like), domestic animals (e.g., dogs and cats), farm animals (e.g., horses, cows, goats, sheep, and pigs) and experimental animal models (e.g., Drosophila, zebra fish, Xenopus, chick, mouse, rat, rabbit, guinea pig, and pig). In some embodiments a mammal is a human. A mammal can be any age or at any stage of development (e.g., an adult, teen, child, infant, or a mammal in utero). A mammal can be male or female. A mammal can be a pregnant female. In certain embodiments, a mammal can be an animal disease model. In some embodiments, the subject is human. In some embodiments, the subject is an animal. In some embodiments, the subject is a plant.

The term “ANAGO” refers to a codon-Adapted Nuclear Argonaute protein. ANAGO is an Argonaute protein variant derived from a microorganism having DNA endonuclease activities. The DNA coding sequences of a microbial Argonaute protein that has DNA endonuclease activities in microorganisms, such as but not limited to, natronobacterium gregoryi [NgAgo], Pyrococcus furiosus [PfAgo], Thermus thermophilus [TtAgo], Methanocaldococcus jannaschii [MjAgo], Clostridium butyricum [CbAgo], or Limnothrix rosea [LrAgo], etc., can be reengineered and adapted with the codons that are most frequently used (with high usage frequency) or have preferential usage in the cells of a eukaryotic species of interest to generate a new synthetic nucleic acid sequence that encodes an ANAGO, that is species-specific to the eukaryotic species. When expressed in a cell in the eukaryotic species, this ANAGO conserves and/or retains an ability to edit a target nucleic acid sequence within the eukaryotic cell. For example, when the most frequently used codons in human cells are used to replace the microbial preferred codons (referring herein to “reengineering” or “adapting”) of a DNA coding sequence of a microbial argonaute protein to generate a new synthetic nucleic acid, which encodes an ANAGO, this type of ANAGO is called human ANAGO. Likewise, when the most frequently used codons or preferentially utilized codons in dog cells are used for reengineering a DNA coding sequence of microbial argonaute protein to generate a new synthetic nucleic acid, which encodes an ANAGO, this type of ANAGO is called dog ANAGO. When the most frequently used codons in plants are used for reengineering a DNA coding sequence of a microbial Argonaute protein to generate a new synthetic nucleic acid, which encodes an ANAGO, this type of ANAGO is called plant ANAGO.

The term “ANAGO” can refer to a protein or to a nucleic acid encoding the protein. For example, when a messenger RNA comprising a synthetic nucleic acid sequence comprises a coding region that encodes an ANAGO in a protein form, the messenger RNA can be called “ANAGO RNA”. The DNA comprising the synthetic nucleic acid sequence that transcribes the ANAGO RNA can be called “ANAGO DNA”. For example, an ANAGO can be an in vitro transcribed messenger RNA. An ANAGO can be cloned into a mammalian expression vector before being introduced into a eukaryotic cell. For example, a human ANAGO in a form of a protein, or an in vitro transcribed messenger RNA, is cloned into a mammalian expression vector before being introduced into a human cell. The expression vector can be a plasmid, a lentiviral vector, an adeno-associated viral vector, or any viral vector.

The name ANAGO is used both in singular or plural with the all letters always capitalized. For example, we say “an ANAGO”, or “two ANAGO”, “these ANAGO”, “a human ANAGO” or “two human ANAGO”, “an ANAGO is used”, or “two ANAGO are used”, and so on.

The Argonaute protein of a microorganism having DNA endonuclease activities (in short “endonuclease activities”) for generating an ANAGO can be from a thermo-bacterium that can tolerate a high temperature of 50-75° C. The ANAGO generated from such a thermo-bacterium can also tolerate a high temperature, such as 50° C., 55° C., >55° C., 50-55° C., 55-60° C., 60-65° C., 65-70° C., 70-75° C., 50-60° C., 60-70° C., 50-70° C., 50-75° C., or any temperature in a range bounded by any of the above values. The Argonaute protein of a microorganism having DNA endonuclease, from which an ANAGO can be derived, can be other microorganisms that are not listed herein.

The ANAGO described herein can be further attached to a Nuclear Localization Signal peptide sequence (NLS) to generate an ANAGO comprising a NLS. This ANAGO comprising a NLS can be further cloned into a eukaryotic expression vector, such as a mammalian expression vector to generate a recombinant ANAGO. This recombinant ANAGO, along with a gene specific donor, with or without a guide oligonucleotide molecule, can be introduced into eukaryotic cells, such as human cells, e.g. HEK293 cells to edit target genomic DNA in a homologous sequence-dependent manner in eukaryotes, such as human. The editing of genome in eukaryotes using species-specific ANAGO can be efficient. The efficiency of the editing of genome in eukaryotic cells, such as human cells, can be at least 1%, at least 5%, 1-60%, 5-60%, 1-70%, 5-70%, 1-80%, 5-80%, 1-90%, 5-90%, 1-100%, 5-100%, more than 1%, more than 5%, 5-10%, 10-15%, 15-20%, 20-25%, 25-30%, 30-35%, 35-40%, 40-45%, 45-50%, 10-20%, 20-30%, 30-40%, 40-50%, 50-60%, 60-70%, 70-80%, 80-90%, 90-100%, 7.1%, 6-8%, 40%, 43%, or any efficiency in a range bounded by any of the above values. The editing of genome in eukaryotic cells, such as human cells, using species-specific ANAGO, such as a human ANAGO can be precise with no significant random insertion and deletion detected. In some embodiments, the homologous recombination directed genome editing in eukaryotic cells, such as human cells, has no off-target events detected.

Either double-stranded or single strand DNA molecules can be used as donor molecules or templates. The homologous donor molecule can have a sequence either short or long. The length of a homology flanking region or arm (5′ and/or 3′) can be as short as 10 nucleotides. The length of a homology arm or flanking region can be as long as 500 or more nucleotides without upper limit. For example, the length of a homology arm or flanking can be 10-500 nucleotides, 20 nucleotides, 10-20 nucleotides, 20-50 nucleotides, 30-100 nucleotides, 50-100 nucleotides, 100-150 nucleotides, 150-200 nucleotides, 200-300 nucleotides, 300-400 nucleotides, 400-500 nucleotides, 400-600 nucleotides, 500-600 nucleotides, 600-700 nucleotides, 100-300 nucleotides, 300-500 nucleotides, 500-700 nucleotides, 700-1000 nucleotides, 150-250 nucleotides, 250-350 nucleotides, 350-450 nucleotides, 450-550 nucleotides, 550-650 nucleotides, 700-800 nucleotides, 800-900 nucleotides, 900-1000 nucleotides, 800-1000 nucleotides, or any number of nucleotides in a range bounded by any of the above values.

In some embodiments, an altered DNA sequence can be embedded between 5′- and 3′-flanking homologous arms. The length of an altered DNA sequence can be as short as a single nucleotide or as long as 1200 or more nucleotides.

In some embodiments, a single-stranded oligonucleotide (e.g. PCSK9 R104C-V114A 70mer

(SEQ ID NO: 5) 5′-CCTGCAGGCCCAGGCTGCC 

GCCGGGGATACCTCACCAAGATCCTG CATG 

CTTCCATGGCCTTCTTCCT-3′, FIG. 1a ) can be chemically synthesized and used as a donor molecule. The donor molecule harbors 1 or multiple base mismatches (boxed bases) to the targeted genomic sequence at a position at least 15 bases away from both the 5′ and 3′ ends of oligo.

In some embodiments, a single-stranded oligonucleotide (e.g. BCR-ABLex6 stop-H3 70mer

(SEQ ID NO: 6) 5′-GGCAGGGGTCTGCACCCGGGAGCCCCCGTTCT 

TCACTGA GTTCATGACCTACGGGAACCTCCTG-3′, FIG. 2a ) can be chemically synthesized and used as a donor molecule. The donor molecule can harbor a restriction enzyme recognition site (boxed sequence) that is inserted into the targeted site and also introduces an in-frame premature stop codon (TAA, bold faced).

In some embodiments, an over 800 bps long donor DNA fragment (e.g. H2Bc-mCherry KI fragment, FIG. 3a ) can be synthesized by using a pair of PCR primers that flanks the both ends of a long exogenous gene fragment with a short stretch of sequence (15 to 50 bases or longer) that is homology to the target site in the genome (e.g. the C terminal coding region of human Histon 2Bc gene, FIG. 3a ).

In some embodiments, a double-stranded large donor DNA fragment can be generated via fusion PCR (e.g. the 1.8 kb of PCSK9-mCherry knock-in fragment to replace the exon 1 sequence of human PCSK9 gene, see FIG. 1a ). The left and right homology arms (over 500 bp long for each one) are generated and fused to an exogenous sequence such as mCherry fragment. The left and right homology regions can be separated by a sequence of 0 to at least 648 bps.

The term “nucleic acid” refers to one or more nucleic acids (e.g., a set or subset of nucleic acids) of any composition from, such as DNA (e.g., complementary DNA (cDNA), genomic DNA (gDNA) and the like), RNA (e.g., message RNA (mRNA), short inhibitory RNA (siRNA), ribosomal RNA (rRNA), tRNA, microRNA, and/or DNA or RNA analogs (e.g., containing base analogs, sugar analogs and/or a non-native backbone and the like), RNA/DNA hybrids and polyamide nucleic acids (PNAs), all of which can be in single- or double-stranded form, and unless otherwise limited, can encompass known analogs of natural nucleotides that can function in a similar manner as naturally occurring nucleotides. In some embodiments a nucleic acid refers to DNA. In some embodiments a nucleic acid refers to RNA. Unless specifically limited, the term encompasses nucleic acids comprising deoxyribonucleotides, ribonucleotides and known analogs of natural nucleotides. A nucleic acid may include, as equivalents, derivatives, or variants thereof, suitable analogs of RNA or DNA synthesized from nucleotide analogs, single-stranded (“sense” or “antisense”, “plus” strand or “minus” strand, “forward” reading frame or “reverse” reading frame) and double-stranded polynucleotides. Nucleic acids may be single or double stranded. A nucleic acid can be of any length of 2 or more, 3 or more, 4 or more, or 5 or more contiguous nucleotides. A nucleic acid can comprise a specific 5′ to 3′order of nucleotides known in the art as a sequence (e.g., a nucleic acid sequence, e.g., a sequence).

A nucleic acid may be naturally occurring and/or may be synthesized, copied or altered (e.g., by a technician, scientist or one of skill in the art). For, example, a nucleic acid may be an amplicon. A nucleic acid may be from a nucleic acid library, such as a gDNA, cDNA or RNA library, for example. A nucleic acid can be synthesized (e.g., chemically synthesized) or generated (e.g., by polymerase extension in vitro, e.g., by amplification, e.g., by PCR). A nucleic acid may be, or may be from, a plasmid, phage, virus, autonomously replicating sequence (ARS), centromere, artificial chromosome, chromosome, or other nucleic acid able to replicate or be replicated in vitro or in a host cell, a cell, a cell nucleus or cytoplasm of a cell in certain embodiments. Nucleic acid provided for processes or methods described herein may comprise nucleic acids comprising 1 to 1000 or more, 1 to 1000, 1 to 500, 1 to 200, 1 to 100, 1 to 50, 1 to 20, or 1 to 10 nucleotides in length. Oligonucleotides are relatively short nucleic acids. Oligonucleotides can be from about 2 to 200, 2 to 150, 2 to 100, 2 to 50, or 2 to about 35 nucleotides in length. In certain embodiments, oligonucleotides are 18 to 30, 20 to 28 or 21-26 nucleotides in length. In some embodiments, oligonucleotides are single stranded. In certain embodiments, oligonucleotides are primers. Primers are often configured to hybridize to a selected complementary nucleic acid and are configured to be extended by a polymerase after hybridizing.

A genome refers to the genetic material of a cell, a virus, or an organism. The genetic material of a cell or organism often comprises one or more genes. In certain embodiments a gene comprises or consists of one or more nucleic acids. The term “gene” means the segment of DNA involved in producing a polypeptide chain and can include coding regions (e.g., exons), regions preceding and following the coding region (leader and trailer) involved in the transcription/translation of the gene product and the regulation of the transcription/translation, as well as intervening sequences (introns) between individual coding segments (exons). A gene may not necessarily produce a peptide or may produce a truncated or non-functional protein due to genetic variation in a gene sequence (e.g., mutations in coding and non-coding portions of a gene). For example, a non-functional gene can be a pseudogene. A gene may also produce a non-coding RNA, such as long non-coding RNA (IncRNA); microRNA (miRNA); small interfering RNA (siRNA); Piwi-interacting RNA (piRNAs); or small nucleolar RNA (snoRNA), and other short RNA (Ma L, Bajic V B, and Zhang Z, “On the classification of long non-coding RNAs”, RNA Biology. 10 (6): 925-33, June 2013). A gene, whether functional or non-functional, can often be identified by homology to a gene in a reference genome. For example, any specific gene (e.g., a gene of interest, a counterpart gene, a pseudogene and the like) of a subject can be identified in another subject, genome or in a reference genome by one of skill in the art. In a diploid subject, a gene often comprises a pair of alleles (e.g., two alleles). Thus, a method, system or process herein can be applied to one or both alleles of a gene. In some embodiments a method, system or process herein is applied to each allele of a gene.

The term “percent identical” or “percent identity” refers to sequence identity between two amino acid sequences. Identity can be determined by comparing a position in each sequence which may be aligned for purposes of comparison. When an equivalent position in the compared sequences is occupied by the same amino acid, then the molecules are identical at that position. When the equivalent site is occupied by the same or a similar amino acid residue (e.g., similar in steric and/or electronic nature), then the molecules can be referred to as homologous (similar) at that position. Expression as a percentage of homology, similarity, or identity refers to a function of the number of identical or similar amino acids at positions shared by the compared sequences. Expression as a percentage of homology, similarity, or identity refers to a function of the number of identical or similar amino acids at positions shared by the compared sequences. Various alignment algorithms and/or programs may be used, including FASTA, BLAST, or ENTREZ. FASTA and BLAST are available as a part of the GCG sequence analysis package (University of Wisconsin, Madison, Wis.), and can be used with, e.g., default settings. ENTREZ is available through the National Center for Biotechnology Information, National Library of Medicine, National Institutes of Health, Bethesda, Md. In one embodiment, the percent identity of two sequences can be determined by the GCG program with a gap weight of 1, e.g., each amino acid gap is weighted as if it were a single amino acid or nucleotide mismatch between the two sequences.

Other techniques for alignment are described in Methods in Enzymology, vol. 266: Computer Methods for Macromolecular Sequence Analysis (1996), ed. Doolittle, Academic Press, Inc., a division of Harcourt Brace & Co., San Diego, Calif., USA. In some embodiments an alignment program that permits gaps in the sequence is utilized to align the sequences. The Smith-Waterman is one type of algorithm that permits gaps in sequence alignments. See Meth. Mol. Biol. 70:173-187 (1997). Also, the GAP program using the Needleman and Wunsch alignment method can be utilized to align sequences. An alternative search strategy uses MPSRCH software, which runs on a MASPAR computer. MPSRCH uses a Smith-Waterman algorithm to score sequences on a massively parallel computer. This approach improves ability to pick up distantly related matches; and is especially tolerant of small gaps and nucleotide sequence errors. Nucleic acid-encoded amino acid sequences can be used to search both protein and DNA databases.

In some embodiments a nucleic acid described herein comprises a label. As used herein, the terms “label” or “labeled” refers to incorporation of a detectable marker, e.g., by incorporation of a radiolabeled amino acid or attachment to a polypeptide of biotin moieties that can be detected by marked avidin (e.g., streptavidin containing a fluorescent marker or enzymatic activity that can be detected by optical or colorimetric methods). In certain embodiments, the label or marker can also be therapeutic. Various methods of labeling polypeptides and glycoproteins can be used. Examples of labels for polypeptides include, but are not limited to, the following: radioisotopes or radionuclides (e.g., ³H, ¹⁴C, ¹⁵N, ³⁵S, ⁹⁰Y, ⁹⁹Tc, ¹²⁵I, ¹³¹I), fluorescent labels (e.g., FITC, rhodamine, lanthanide phosphors), enzymatic labels (e.g., horseradish peroxidase, β-galactosidase, luciferase, alkaline phosphatase), chemiluminescent, biotinyl groups, predetermined polypeptide epitopes recognized by a secondary reporter (e.g., leucine zipper pair sequences, binding sites for secondary antibodies, metal binding domains, epitope tags). In certain embodiments, labels are attached by spacer arms of various lengths to reduce potential steric hindrance.

In some embodiments, a carrier, radioisotope and/or a polypeptide can be indirectly or directly associated with, or bound to (e.g., covalently bound to, or conjugated to), a nucleic acid described herein. In certain embodiments agents or molecules are sometimes conjugated to or bound to nucleic acids to alter or extend the in vivo half-life of a nucleic acid or fragment thereof. In some embodiments, a nucleic acid described herein is fused or associated with one or more polypeptides (e.g., a toxin, ligand, receptor, cytokine, antibody, the like or combinations thereof).

In certain embodiments, presented herein is a nucleic acid that encodes and/or expresses an Argonaute protein or Argonaute polypeptide or a functional fragment thereof. An Argonaute protein or Argonaute polypeptide is a DNA-guided endonuclease that can edit nucleic acids within a cell or subject (e.g., within a genome of a subject) in a target specific manner.

In some embodiments, an ANAGO comprises a polypeptide encoded by the sequence of SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, or SEQ ID NO:4. In certain embodiments, an ANAGO comprises an amino acid sequence having 70% to 100% identity, 80% to 100% identity, 90% to 100% identity or 95% to 100% identity, 70-80% identity, 80-90% identity, 90-100% identity, 70-75% identity, 75-80% identity, 80-85% identity, 85-90% identity, 90-95% identity, 95-100% identity, at least 70% identity, at least 75% identity, at least 80% identity, at least 85% identity, at least 90% identity, at least 95% identity, at least 98% identity, at least 99%, or 100% identity to a polypeptide encoded by the sequence of SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, or SEQ ID NO:4, or a portion thereof. In certain embodiments, an ANAGO conserves and/or retains an ability to edit a target nucleic acid sequence (e.g., RNA, DNA, a gene, promoter or the like) within a eukaryotic cell (e.g., a cell of a subject) in a target specific manner. The ability to edit a target sequence within a genome of a subject refers to an ability to insert, remove and/or replace one or more specific nucleotides within a target sequence of a cell (e.g., a human cell).

Argonaute (Ago) proteins are small RNA or DNA guided, site-specific endonucleases, which are present in all three kingdoms of life. The various functions of Argonaute proteins have been studied extensively. Recent studies have suggested that prokaryotic Argonautes are involved in identifying foreign genetic elements in a sequence specific manner and/or in the recruitment of nucleases. Many DNA coding sequences of prokaryotic Argonaute proteins, such as NgAgo, PfAgo, TtAgo, MjAgo, CbAgo, or LrAgo, etc. can be reengineered and adapted to generate an ANAGO that is species-specific in a eukaryote. The microbial preferred codons can be changed to human preferred codons, such as a codon with a frequency of at least 1 per thousand, at least 2 per thousand, at least 3 per thousand, at least 4 per thousand, at least 5 per thousand, at least 6 per thousand, at least 7 per thousand, at least 8 per thousand, at least 9 per thousand, at least 10 per thousand, at least 11 per thousand, at least 12 per thousand, at least 13 per thousand, at least 14 per thousand, at least 15 per thousand, at least 16 per thousand, at least 17 per thousand, at least 18 per thousand, at least 19 per thousand, at least 20 per thousand, at least 21 per thousand, at least 22 per thousand, at least 23 per thousand, at least 24 per thousand, at least 25 per thousand, at least 26 per thousand, at least 27 per thousand, at least 28 per thousand, at least 29 per thousand, at least or 30 per thousand, at least 31 per thousand, at least 32 per thousand, at least 33 per thousand, at least 34 per thousand, at least 35 per thousand, at least 36 per thousand, at least 37 per thousand, at least 38 per thousand, at least 39 per thousand, at least 40 per thousand, to generate a human ANAGO.

In certain embodiments, a nucleic acid is configured to express a polypeptide in a mammalian cell. A nucleic acid that is configured to express a polypeptide (e.g., an ANAGO) comprises one or more nucleic acid regulatory sequences that direct the expression of a polypeptide in a cell. Accordingly, a nucleic acid that is configured to express a desired polypeptide, such as ANAGO, may include one or more of a coding region that encodes the desired protein, such as ANAGO, one or more suitable promoters operably linked to the coding region, a translation initiation sequence, a start codon, a stop codon, a polyA signal sequence, a leader sequence, a nuclear localization sequence, and the like. In certain embodiments, a nucleic acid comprises a sequence that encodes a nuclear localization signal (NLS) sequence. Any suitable NLS sequence can be used. One non-limiting example of an NLS sequence is SV40 nuclear localization signal (NLS) sequence. In certain embodiments, a nucleic acid is configured to express an ANAGO, or functional fragment thereof.

A target sequence refers to a specific location (a specific nucleic acid sequence) within the genome of an organism or a cell that one intends to modify using a composition or method described herein. In some embodiments, a target sequence is a nucleic acid located within a genome of a cell or an organism. In some embodiments, a target sequence comprises RNA. In certain embodiments, a target sequence comprises DNA. In some embodiments, a target sequence contains 1 or more nucleotides in length. In some embodiments, a target sequence can be as long as a few thousands or even millions base pairs in length, if it is in a linear contiguous DNA sequence in a chromosome. In certain embodiments, a target sequence is 1000 to 10,000, 5000-10,000, 1000 to 5000, 500 to 1000, 700-1000, 500-700, 100 to 900, 100 to 500, 100 to 300, 100 to 200, 50 to 100, 10 to 100, 200-300, 300-400, 400-500, 500-600, 600-700, 700-800, 800-900, 900-1000, 1000-2000, 2000-3000, 3000-4000, 4000-5000, 5000-6000, 6000-7000, 7000-8000, 8000-9000, 9000-10,000, 10-50, 16 to 50, 16 to 30, 16 to 20, 18 to 50, 18 to 30, 18 to 28, 18 to 25, 18 to 26, 18-20, 19-50, 19-30, 19 to 26, 19 to 25, 19-20, 20 to 30, 20 to 25, 20 to 24, 21 to 24, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, or 50 nucleotides in length, or any number in a range bounded by any of the above values of nucleotides (nt) or base pairs (bp) in length and may be located within a gene, exon, intron or any suitable portion of a genome. Any nucleotide within a target sequence or any portion of a target sequence can be modified by a method described herein. Any number of nucleotides within a target sequence may be deleted, mutated or replaced, for example by a desired sequence (e.g., an insert sequence of a donor sequence). In some embodiments, one or more nucleotides or a desired sequence are inserted into a target sequence by a method described herein. In certain embodiments, a target sequence provides a nucleic acid sequence that is complementary or identical to a guide oligonucleotide, or portion thereof, for example when the guide oligonucleotide is used in an experiment for comparison purpose as described below. In certain embodiments a target sequence provides a nucleic acid sequence that is complementary or identical to a 5′ and/or 3′ flanking regions of a donor sequence.

Although a guide oligonucleotide is not needed in the ANAGO induced gene editing technology, a guide molecule was used in some of the experiments described in FIG. 2b and FIG. 4b , solely for comparing the results in the experiment where a guide molecule was not used. A guide oligonucleotide often comprises a nucleic acid sequence that is 80% to 100% identical to the target site. A guide oligonucleotide is sometimes a nucleic acid that is 18 to 30 bases in length. Without being limited to theory, an ANAGO described herein can utilize a guide oligonucleotide to cut the genomic DNA of an organism or cell at a specific target sequence that is defined by the sequence of a guide oligonucleotide. In certain embodiments, an ANAGO cleaves a target nucleic acid sequence anywhere within a sequence defined by a guide oligonucleotide. In some embodiments, an ANAGO cleaves a target site at a location defined by any one of the first 10 nucleotides (5′-nucleotides) of a guide oligonucleotide. When both a guide oligonucleotide and a donor nucleic acid are present, an ANAGO will proceed to replace the targeted sequence with a donor nucleic acid into the genome of a cell at a target site defined by the guide oligonucleotide. If a donor sequence is not present, an ANAGO loaded with a guide oligonucleotide, will often cleave a target site defined by the guide oligonucleotide sequence. This process often results in the introduction of one or more single nucleotide mutations introduced at the target site (e.g., see Example 3).

In some embodiments, there are several advantages to not using a guide molecule in the ANAGO induced precise genomic sequence editing (AISE) technology disclosed herein. First, the percentages of on-target HDR precise editing using the AISE in the presence of a guide molecule and a donor molecule is lower than that of the AISE in the presence of a donor molecule alone without a guide molecule. The difference in the percentages of on-target HDR precise editing between the AISE with a guide molecule and the AISE without a guide molecule can be significant. In some embodiments, the percentages of on-target HDR precise editing using AISE in the presence of a guide molecule and a donor molecule is about 1-10 times, about 1-6 times, about 1-5 times, about 1-4 times, about 1-3 times, about 1 times, about 2 times, about 3 times, about 4 times, about 5 times, about 6 times, about 7 times, about 8 times, about 9 times, about 10 times, about 1%-40%, about 1%-30%, about 1%-20%, about 1%-10%, about 10%-20%, about 20%-30%, about 1%-5%, about 1%-4%, about 1%-3%, about 1%-2%, about 2%-3%, about 3%-4%, about 4%-5%, about 5%-6%, about 6%-7%, about 7%-8%, about 8%-9%, about 9%-10%, about 10%-15%, about 15%-20%, about 20%-25%, about 25%-30%, about 5%-10%, about 1%, about 2%, about 3%, about 3.2%, about 5%, about 10%, about 15%, about 15.3%, or about 20% lower than that of the AISE in the presence of a donor molecule alone without a guide molecule, or any percentage bounded by any of the above values. It is possible that the guide molecule in the AISE described herein may compete with the donor molecule during the sequence editing. Therefore, not only is a guide molecule not required for ANAGO induced precise genomic sequence editing (AISE), but there may also be an advantage in not using a guide molecule in the AISE described herein in achieving precise genomic editing with high yield/percentage.

Furthermore, to prepare a guide molecule that is specific to each given target sequence and to incorporate the guide molecule in AISE requires additional material, synthesis time, purification time, and steps. This may be more time consuming and inconvenient, which would certainly increase overall treatment cost and prolong the overall treatment time when AISE is applied in gene therapy for treating gene related various diseases, disorders, or conditions.

A donor sequence (a donor fragment) is a nucleic acid comprising three parts, a 5′ flanking sequence, a desired sequence, and a 3′ flanking sequence. In some embodiments, a donor sequence comprises RNA. In certain embodiments, a donor sequence comprises DNA. In some embodiments, a donor sequence is single stranded. In some embodiments, a donor sequence is double stranded. A donor sequence can be short or long in length.

The 5′-flanking sequence and the 3′-flanking sequences are different sequences. In some embodiments, the 5′-flanking sequence and the 3′-flanking sequences do not share more than 10% identity. In some embodiments, the 5′-flanking sequence and the 3′-flanking sequences are located on opposite sides of the desired sequence. Each of 5′ flanking sequence and/or each of 3′ flanking sequence of a donor sequence, in certain embodiments, is independently about 500 nucleotides (nt) or base pairs (bp) in length, or longer, about 100 nt or bp or longer, 100-200 nt or bp, 10-200 nt or bp, 10-100 nt or bp, 10-75 nt or bp, 75-100 nt or bp, 10-50 nt or bp, 19-50 nt or bp, 19-30 nt or bp, 16-50 nt or bp, 16-30 nt or bp, 10-25 nt or bp, 20-25 nt or bp, 10-20 nt or bp, 20-30 nt or bp, 30-40 nt or bp, 40-50 nt or bp, 50-60 nt or bp, 60-70 nt or bp, 70-80 nt or bp, 80-90 nt or bp, 90-100 nt or bp, 10-15 nt or bp, 15-25 nt or bp, 25-35 nt or bp, 35-45 nt or bp, 45-55 nt or bp, 55-65 nt or bp, 65-75 nt or bp, 75-85 nt or bp, 85-95 nt or bp, 95-100 nt or bp, 16-20 nt or bp, 20-25 nt or bp, 25-30 nt or bp, 30-35 nt or bp, 35-40 nt or bp, 40-45 nt or bp, 45-50 nt or bp, 50-55 nt or bp, 55-60 nt or bp, 60-65 nt or bp, 65-70 nt or bp, 70-75 nt or bp, 75-80 nt or bp, 80-85 nt or bp, 85-90 nt or bp, 90-95 nt or bp, 19-50 nt or bp, 19-30 nt or bp, 16-20 nt or bp, 10 nt or bp, 11 nt or bp, 12 nt or bp, 13 nt or bp, 14 nt or bp, 15 nt or bp, 16 nt or bp, 17 nt or bp, 18 nt or bp, 19 nt or bp, 20 nt or bp, 21 nt or bp, 22 nt or bp, 23 nt or bp, 24 nt or bp, 25 nt or bp, 26 nt or bp, 27 nt or bp, 28 nt or bp, 29 nt or bp, 30 nt or bp, 31 nt or bp, 32 nt or bp, 33 nt or bp, 34 nt or bp, 35 nt or bp, 36 nt or bp, 37 nt or bp, 38 nt or bp, 39 nt or bp, 40 nt or bp, 41 nt or bp, 42 nt or bp, 43 nt or bp, 44 nt or bp, 45 nt or bp, 46 nt or bp, 47 nt or bp, 48 nt or bp, 49 nt or bp, 50 nt or bp, 51 nt or bp, 52 nt or bp, 53 nt or bp, 54 nt or bp, 55 nt or bp, 56 nt or bp, 57 nt or bp, 58 nt or bp, 59 nt or bp, 60 nt or bp, 61 nt or bp, 62 nt or bp, 63 nt or bp, 64 nt or bp, 65 nt or bp, 66 nt or bp, 67 nt or bp, 68 nt or bp, 69 nt or bp, 70 nt or bp, 71 nt or bp, 72 nt or bp, 73 nt or bp, 74 nt or bp, 75 nt or bp, 76 nt or bp, 77 nt or bp, 78 nt or bp, 79 nt or bp, 80 nt or bp, 81 nt or bp, 82 nt or bp, 83 nt or bp, 84 nt or bp, 85 nt or bp, 86 nt or bp, 87 nt or bp, 88 nt or bp, 89 nt or bp, 90 nt or bp, 91 nt or bp, 92 nt or bp, 93 nt or bp, 94 nt or bp, 95 nt or bp, 96 nt or bp, 97 nt or bp, 98 nt or bp, 99 nt or bp, or 100 nt or bp in length, or any number in a range bounded by any of the above values of nucleotides (nt) or base pairs (bp) in length. Each of the 5′-flanking sequence and each of the 3′-flanking sequence independently comprise at least 10 nucleotides that are identical to the target sequence.

The term “desired sequence” is used synonymously with the terms “desired nucleic acid” and “desired nucleic acid sequence”. For purposes of clarity, a “desired sequence” may sometimes be referred to as an “insert sequence”. In some embodiments, a desired sequence comprises RNA. In certain embodiments, a desired sequence comprises DNA. A desired sequence can be any suitable sequence of any suitable length.

Vehicles for Delivery

The ANAGO described herein is small enough that it can be introduced into eukaryotic cells via numerous mechanisms and tools, and examples of which, but not limited to, are shown below. An ANAGO can be delivered into a mammalian cell directly in a complete protein form or in a form of nucleic acid after the ANAGO is cloned to an expression vector, such as a mammalian expression vector.

(i) Viral Vector

ANAGO in a form of DNA or RNA can be housed in the capsid of a virus that is known to successfully, or preferentially, or selectively infect a specific cell type under ordinary or laboratory conditions. Injection of the ANAGO-loaded viral particles leads to infection of the target cells and injection of the desired ANAGO into the host cell. The translational machinery and ribosomes proceed to translate the ANAGO into functional argonaute proteins ready for gene-editing. As the virus spreads, more cells become infected and the quantity of argonaute protein produced increases proportionally. The argonaute complex produced can proceed to execute the pre-programmed gene-editing process it was designed for in the target tissues or cells in an organism. This is a preferred method for non-clinical settings, research settings, and for large quantities of cells in vivo or in vitro.

(ii) Electroporation

Target cells are placed in a dish or plate for in vitro exposure to the ANAGO in a form of RNA. Electric pulses are sent through the plate in order to render the membranes of the target cell porous. ANAGO of interest can flow through these pores into the target cells and reach the translational machinery. The ANAGO and donor nucleic acid are then assembled and ready for editing.

(iii) Lipofection

Nucleic acids can be packaged in spherical molecules composed of lipids. These lipids can fuse with lipophilic cellular membranes and dump the nucleic acid payload into the cell. The component parts can then be assembled into the ANAGO for genome editing.

(iv) Nucleofection

A variation of many electroporation protocols used to allow nucleic acids to reach the nucleus, can be used to transport ANAGO into the cell/nucleus for transcription and/or translation into the ultimate active protein product.

(v) Nanoparticle

New formulations of nanoparticles are constantly being developed that can deliver payloads such as the ANAGO into a cell/nucleus. Colloidal gold nanoparticles for example can be used for this purpose safely and efficiently.

(vi) Microinjection

In larger cell types, direct injection of the ANAGO is possible. This method can be used when only a few cells are targeted.

EXAMPLES

A. Construction of Human ANAGO

The ability to introduce a nucleic acid (e.g., a gene, heterologous DNA or modified nucleic acid) into a genome of an organism at a specific targeted locus is a powerful tool for therapeutic and research purposes. The user-friendly CRISPR-Cas9 is very efficient in making mutations via non-homologous end joining (NHEJ) in human cancer cell lines such as 293T cells. However, it can mediate homologous recombination (HR) only at a much low efficiency (2-5%) in 293T cells and even lower in other biologically relevant cells such as human induced pluripotent stem cells (iPSCs). Gao et al. in a retracted publication (Gao F, et al., (2016) Nat. Biotechnol. 34(7):768-73) reported that it is feasible to achieve genome editing in human cells by using Natronobacterium gregoryi Argonaute (NgAgo) with a guide DNA oligo. However, multiple labs have failed to reproduce this phenomenon claimed by Gao et al. thus far, which led to the withdrawal of this publication later by Gao et al. Gao et al. use the sequence of the NgAgo in their publication.

To investigate whether the ANAGO described herein could be used as a novel and practical gene editing tool in mammalian cells, we reasoned that it is plausible for microbial argonaute proteins to mediate gene editing in human cells, but at a very low efficiency to be detectable. Particularly, since most of reported DNA targeting argonaute proteins are the products of either bacterial or archaeal microorganisms, their preference of codon usage is significantly different from the ones used in the translation machinery of human cells. It is known that codon usage is a rate-limiting factor for efficient translation and proper folding of a protein in an organism-specific manner. Therefore, we reengineered and adapted the DNA coding sequences of microbial argonaute proteins that have DNA endonuclease activities in microbial cells, such as NgAgo, PfAgo, TtAgo and MjAgo, with the codons that are most frequently used in human cells (as described above), to generate humanized argonaute variants, that comprises, conserves, and/or retains an ability to edit a target nucleic acid sequence within a human cell when expressed in the human cell. We name this type of reengineered and adapted argonaute variant “ANAGO”. ANAGO is species-specific. When ANAGO comprises the codons that are preferentially used in human cells, we call it human ANAGO.

In order to introduce the ANAGO into the nucleus of mammalian cells, we fused a SV40 nuclear localization signal peptide sequence (NLS) to the N-terminus of the protein in ANAGO. A small Human influenza hemagglutinin (HA) tag was also included for protein detection purposes. The DNA coding sequences of the human ANAGO, attached to a NLS and a HA tag and derived from (a) NgAgo, (b) PfAgo, (c) TtAgo, and (d) MjAgo, are shown below, wherein the HA epitope tag sequence is framed; and the SV40 nuclear localization signal (NLS) sequence is underlined.

ANAGO Induced Homologous Recombination Directed Genome Editing in Eukaryotes Materials and Methods

Constructs of ANAGO expression cassette: The ANAGO encoded with the humanized DNA sequence of NLS-NgAgo ORF, or HA-NLS-PfAgo ORF, or HA-NLS-TtAgo ORF, or HA-NLS-MjAgo ORF was chemically synthesized and fused to the P2A-YFP cDNA cassette. The expression of fusion open reading frame was driven by EF1alpha promoter in a mammalian expression vector (SynBio Tech, New Jersey).

Cell culture and transfection. HEK293 (ATCC catalog # CRL-1573) cells were maintained in a DMEM high glucose medium supplemented with 10% fetal bovine serum and 100 U/ml penicillin and 100 ug/ml streptomycin. Cells were seeded into 12-well plates one day before transfection. Cells were transfected at about 50% confluence using LIPOFECTAMINE™ 3000 (Thermo Scientific). Specifically, HEK293 were transfected with 1000 ng of a human ANAGO-expressing plasmid plus certain amount of donor DNA fragment that is dependent on its size (for examples, 240 ng of 1.8 kb PCSK9-mCherry knock-in fragment or 200 nM of single-stranded oligonucleotide PCSK9 R104C-V114A 70mer for PCSK9 gene in example 1, see FIG. 1a ). Cells were harvested for genomic DNA extraction 72 hours post transfection. The donor fragment directed genomic editing event was identified and confirmed by PCR. Subsequently, the genomic PCR products are sequenced and analyzed.

We have used a few human ANAGO described herein to induce homologous recombination directed genome editing in human cells successfully. We have discovered that the use of the human ANAGO to induce genome editing in human cells does not require the presence of a guide DNA molecule. ANAGO induced genome editing is highly precise and produces very low numbers of associated indel events in the target site in all cases tested. Selected examples of using an ANAGO-induced sequence editing (AISE) technology to modify genes in human cells are shown below.

Example 1. Human PCSK9

Proprotein convertase subtilisin/kexin type9 (PCSK9), acts in lipoprotein homeostasis. It binds and removes low-density lipoprotein receptors (LDLR). If not binding PCSK9, LDLR will return to the cell surface and can continue to remove LDL-particles from the bloodstream. Agents which block PCSK9 can lower LDL particle concentrations. Significantly, individuals with complete naturally occurring heterozygous loss-of-function (LOF) mutations of PCSK9 gene have a near 88% reduced risk of developing cardiovascular complications over a 15-year follow-up period [Cohen J C, Boerwinkle E, et al, 2006, NEJM 354:1264-1272]. Moreover, carriers of LOF mutations such as deltaR97+Y142X, C679X, and R104C+V114A were found to lack PCSK9 expression. These individuals with natural occurring LOF mutations have very low LDL levels in their blood stream without association with any obvious deleterious effects. This supports the clinical utility of introducing LOF mutations to PCSK9 through gene editing to treat hypercholesterolemia.

To test if ANAGO induced sequence editing (AISE) technology described herein could be used to introduce specific PCSK9 LOF mutations in mammalian cells, we first constructed a donor molecule via fusion PCR, which contains the mCherry coding sequence flanked by the homology regions to the exon 1 and intron 1 sequence of PCSK9 gene on the left and right sides respectively. The homology directed replacement (HDR) of the mCherry fragment removes the entire exon 1 as well as 88 bps of the intron 1 sequence of PCSK9 (FIG. 1a ). The protein expression constructs of human ANAGO (NLS-NgAgo ORF, HA-NLS-PfAgo ORF, and HA-NLS-TtAgo ORF) and the donor molecule were co-transfected into HEK293 either with or without a guide oligo PCSK9-GD8S (5′-TGGGTCCCGCGGGCGCCCGTGCGC-3′ (SEQ ID NO: 7)) that targets exon 1 by using LIPOFECTAMINE™ 3000. The cellular genomic DNA was harvested at 72 hours post transfection. PCR of genomic DNA samples was carried out to identify the mCherry knock-in event by pairing a donor mCherry specific primer (mCherry-For: 5′-CCTTTCCCACAACGAGGACT-3′ (SEQ ID NO: 8)) with a flanking region of PCSK9 specific primer (PCSK9-in1-R3: 5′-CGAGAATACCTCCGCCCCTT-3′ (SEQ ID NO: 9)), which is located outside of the right homology arm (FIG. 1b ). The genomic PCR product was only detectable from the cell samples that were transfected with an ANAGO expression construct and the 1.8 kb of mCherry KI donor fragment either with or without the guide oligo, but not in the absence of the donor fragment (FIG. 1b ).

In a separate experimental setting, instead of using an over 500 bps long and double stranded homologous sequence as a flanking arm to facilitate HDR, we tested whether a short and single-stranded oligodeoxynucleotide, PCSK9 R104C-V114A 70mer

(5′-CCTGCAGGCCCAGGCTGCC 

GCCGGGGATACCTCACCAAGATCCTG CATG 

CTTCCATGGCCTTCTTCCT-3′ (SEQ ID NO: 5)), which mimics R104C (CGC>TGC)+V114A (GTC>GCC) LOF mutant allele sequence of human PCSK9 gene, could be used as a donor template. The mutated bases are located at the 20th and 40th positions of the 70mer respectively. To estimate the relative frequency of sequence exchanging in the transfected cells, a pair of primers (PCSK9 F9: 5′-GCTTTTTGGTCCGCATTTGG-3′ (SEQ ID NO: 10) and PCSK9 R9: 5′-GGCTCTACCCCTAGCTGTCT-3′ (SEQ ID NO: 11)) located outside of the donor target region was used to generate the genomic PCR product for Sanger sequencing analysis. The results indicated that about 7.1% of genomic PCR products contained the intended R104C+V114A mutation incorporated into the PCSK9 allele in HEK293 cells (FIG. 1c ). This result also validates the notion that a short homologous region of 19 bases on each side of modified bases is long enough to generate a desired HDR. In addition, we tested another single-stranded oligo 89mer, PCSK9 Y142X-E144X_donor89_Bgl2

(5′-TCTCTGGCTTCTGCAGGCCTTGAAGTTGCCCCATGTCGACT

AGGAGGACTCCTCTGTCTTTGCCCAGAGCATCCCGTGGAACC- 3′ (SEQ ID NO: 12)), which introduces LOF mutations Y142X (TAC>TAG) and E144X (GAG>TAG) as well as a Bgl2 site (underlined bases) into the exon 3 sequence of PCSK9 gene (FIG. 1a ). The Y142X LOF mutation of PCSK9 was found naturally in an African American woman, who has no detectable PCSK9 expression but apparently in good health. Her circulating LDL level is at 0.36 mM, which is about 8-fold lower than normal (Zhao Z, et al., Am J Hum Genet. 2006; 79:514-523). A pair of specific PCR primers (PCSK9 F8 primer 5′-CCGTGTTGCAGGGATATGGG-3′ (SEQ ID NO: 13) and PCSK9 R8 primer 5′-CATTTGTGGGGCAACAGGAAG-3′ (SEQ ID NO: 14)) located in the flanking introns were used to generate a 541 bp PCR amplicon for sequencing analysis. In this case, 3% of amplicon were the HDR product, meanwhile, the non-HDR indel incidence was nearly undetectable (FIG. 1d ). These studies suggest that AISE technology could be used to specifically inactivate PCSK9 gene and thus to reduce the circulating LDL level in patients with hypercholesterolemia.

Example 2. Human ABL1

The Philadelphia (Ph) translocation t(9;22)(q34;q11) leads ABL1 to fuse with BCR. The resulting BCR-ABL fusion gene is the main reason causing chronic myelogenous leukemia (CML) and Ph+ acute lymphoblastic leukemia (ALL). BCR-ABL encodes a constitutively active cytoplasmic tyrosine kinase that is necessary and sufficient to induce and maintain leukemic transformation. The age-adjusted incidence is 1.6 per 100,000 population members. Small molecular inhibitors have been developed to inhibit BCR-ABL activity. However, drug resistance often occurs in many patients receiving treatment.

Since the main cause of disease is the hyper kinase activity of the fusion protein, an insertion of a premature stop codon in the front of the coding region of kinase domain should result in a truncated product that lacks the kinase domain and thereby inactivates the BCR-ABL fusion gene. A precise gene editing with an AISE approach described herein to inactivate the fusion gene could be done ex vivo with a patient's bone marrow hematopoietic stem cells (HSCs). This approach may cure the disease permanently for CML and Ph+ ALL patients.

BCR-ABLex6stop-H3, a single-stranded oligodeoxynucleotides 70mer

(5′-GGCAGGGGTCTGCACCCGGGAGCCCCCGTTCTAAGCTTTCACTGAG TTCATGACCTACGGGAACCTCCTG-3′ (SEQ ID NO: 6)), which changed ABL1 residue Tyr312 codon TAT to a stop codon TAA as well as introduced a Hind III site, which was designed and synthesized. The engineered site is flanked by 32 nucleotides of short homology sequence on each side of the 70mer donor oligo (FIG. 2a ). To test whether the 70mer of single-stranded oligo harboring 5 altered bases could be used as a donor molecule to introduce the compound stop codon/Hind III site into the precise target site of ABL1 exon 6 of human genome, we co-transfected a human ANAGO expression construct together with the donor oligo BCR-ABLex6stop-H3 70mer into HEK293 cells. The genomic DNA of transfected cells was harvested at 96 hours post transfection. The genomic region containing the target site was amplified by PCR with a pair of specific primers (ABL-F1: 5′-GCGTCTGAATTCTGTGGCAG-3′ (SEQ ID NO: 15) and ABL-R1: 5′-CTTTGCCAGGAGCCTAGTGT-3′ (SEQ ID NO: 16)) and the PCR products were subsequently sequenced. The result indicated that highly efficient and precise editing was achieved. The on-target integration of donor sequence was detected in 43% of genomic PCR products of the cells transfected with the ANAGO expression construct based on NgAgo, meanwhile the non-HDR indel incidence was less than 1% (FIG. 2b ). The integration of TAAGCTT (stop/Hind III) mutation sequence was further confirmed (FIG. 2c ). In order to have a comprehensive assessment of editing events, a 429 bp of PCR amplicon of target site was generated by using a pair of primers (ABL-F2: 5′-TTGGGACCATGTTGGAAGTT-3′ (SEQ ID NO: 17) and ABL-R2: 5′-AGCACTGAGGTTAGAAGCTG-3′ (SEQ ID NO: 18)). The amplicon product was subjected to the Next Generation Sequencing (NGS) (Amplicon-EZ NGS service was provided by GeneWiz, NJ). The total sequence reads were more than 30,000 for each amplicon sample. For the cells transfected with the ANAGO expression construct based on NgAgo, 32.0% of 32,207 sequence reads belong to the precise on-target HDR editing events. In the cells transfected with the other protein expression constructs of the human ANAGO, such as HA-NLS-PfAgo ORF, HA-NLS-TtAgo ORF, and HA-NLS-MjAgo ORF, the percentages of on-target HDR precise editing reads were 23.5%, 19.5% and 10.3% respectively (Table 1). The result also confirmed that the unintended indel events commonly associated with a DNA double-strand break (DSB) were rare, less than 1%.

Our data indicates the potential clinical application of the AISE technology disclosed herein for the cure of CML and Ph+ ALL by permanently inactivation of BCR-ABL oncogene in hematopoietic stem cells isolated from these patients.

Example 3. Human Histone 2Bc

Histone 2Bc gene is an intronless and house-keeping gene. It encodes a histone 2B subunit. In this example, we want to expand the potential application of the AISE technology. Particularly, we want to see if a short homologous flanking sequence, for example, as short as 50 bps could be used to facilitate the knock-in of a large exogenous DNA fragment (>700 bp) in mammalian cells. We generated a donor fragment H2Bc-mCherry KI by using mCherry ORF

(H2Bc-LH50-mCHer: 5′-ACGCAGTGTCCGAAGGTACCAAGGCTGTC ACCAAGTATACAAGCTCCAAGATGGTGAGCAAGGGCGAG-3′ (SEQ ID NO: 19); and mCHer-H2Bc-RH50: 5′-GTGGCTCTGAAAAGAGC CTTTGAGTTTTAAAGCACCTAAGCACACATTTACTTGTACAGCTCGTCCA TGC-3′ (SEQ ID NO: 20)) that incorporated 50 bp of H2Bc sequence as flanking arm on each side of the amplified mCherry fragment. The insertion of donor fragment would result in the in-frame fusion of mCherry open reading frame (ORF) to the last codon of H2Bc (FIG. 3a ). The precise integration was detected by genomic PCR reactions with primer pairs H2Bc-F1/mCherry-Rev (H2Bc-F1: 5′-TAACGACATCTTCGAGCGCA-3′ (SEQ ID NO: 21); and mCherry-Rev: 5′-TACGACACTGCATTACGGGG-3′ (SEQ ID NO: 22)) and mCherry-For/H2Bc-R1 (mCherry-For: 5′-CCTTTCCCACAACGAGGACT-3′ (SEQ ID NO: 8); and H2Bc-R1: 5′-TGTGAGACTTGAGTGGCTCTG-3′ (SEQ ID NO: 23)) that amplified the 5′ and 3′ junctional regions respectively. The three human ANAGO constructs (NLS-NgAgo ORF, HA-NLS-PfAgo ORF, and HA-NLS-TtAgo ORF) were all able to facilitate the precise knock-in of mCherry in Histon 2Bc (FIG. 3b ). Moreover, the expression of H2Bc-mCherry fusion protein was observed in live cells 72 hours post transfection (FIG. 3c ).

Example 4. Human CD274/PD-L1

High expression of PD-L1, which is also known as CD274, has been associated with tumor cells in advanced stage tumors such as liver cancer (Xu Y, Poggio M, Jin H Y, etc. (2019) Translation control of the immune checkpoint in cancer and its therapeutic targeting. Nature Medicine, 25, 301-311). PD-L1 blockade is a potential form of cancer immunotherapy. It aims to disrupt the activation of the PD-1/PD-L1 axis, which is likely to serve as a mechanism for tumor evasion of host tumor antigen-specific T-cell immunity. In this example, we explored the possibility to inactivate PD-L1 permanently in a tumor cell by AISE approach. A single-stranded oligo CD274-HDR1 72mer donor molecule

(5′-GTGAAATTGCAGGATGCAGGGGTGTACCGCAAGCTTGCTAGCGCAT GATCAGCTATGGTGGTGCCGACTACA-3′ (SEQ ID NO: 24)) was designed to introduce a premature stop codon as well as Hind III and Nhel sites into the exon 3 region of human CD274 gene (FIG. 4a ). We co-transfected donor DNA and plasmid DNA of a humanized ANAGO expression construct into HEK293 cells. The genomic DNA of transfected cells was harvested at 96 hours post transfection. The genomic region containing the entire exon 3 was amplified by PCR with a pair of specific primers (CD274-F3: 5′-AGCATTTACTGTCACGGTTCCC-3′ (SEQ ID NO: 25) and CD274-R2: 5′-AAAGATCAGGCCTCTCATCTATAA-3′ (SEQ ID NO: 26)) for amplicon deep-sequencing (GeneWiz, New Jersey). The data analysis revealed that over 18% reads showed the on-target HDR editing in the exon 3 of CD274 gene in HEK293 cells transfected with the human ANAGO construct derived from PfAgo sequence (FIG. 4b ).

In order to evaluate the difference between the AISE with both a guide molecule and a donor molecule and the AISE with a donor molecule alone without a guide molecule, a separate comparison experiment under the same condition as above with the exception of the addition of a guide molecule (5′-TGCAGGGGTGTACCGCTGCATGAT-3′ (SEQ ID NO: 27)) that is targeted to the desired mutation site (FIG. 4c ) in the presence of the donor molecule described above. In this case, the deep-sequencing data analysis revealed that only 2.7% of the reads showed the desired on-target HDR editing in the exon 3 of CD274 gene in HEK293 cells transfected with the human ANAGO construct derived from PfAgo sequence (FIG. 4c ).

Based on the above results, the percentage of the total HDR and/or the precise HDR using AISE in the presence of both a guide molecule and a donor molecule was significantly reduced as compared to that of the AISE using a donor molecule alone without a guide molecule, >18% vs 2.7% respectively. These results clearly demonstrate that not only is a guide molecule not required for ANAGO-induced precise genomic sequence editing (AISE), but also the addition of a guide molecule in the AISE system may lead to significantly lower percentage of desired HDR as compared to AISE system with a donor molecule alone without a guide molecule. These data showed feasibility of using the AISE technology disclosed herein without a guide molecule to enhance natural immune response by inactivating PD-L1 gene in tumor tissues, and apparent advantages without using a guide molecule.

Perspectives of AISE Technology or Approach

Unlike Cas proteins, which only exist in prokaryotes, Argonaute proteins are conserved through evolution and can be identified in virtually all species. In mammalian cells, endogenous Argonaute proteins are considered to be a major component of the RNA-induced silencing complex (RISC), which mediates RNA interference. Argonaute uses a micro RNA (22 nt) as a guide for identifying complementary target mRNA. Interestingly, an evolutionarily related enzyme in prokaryotes, Argonaute of the bacterium Thermus thermophiles (TtAgo), was found to be able to use DNA-guided DNA interference as a defense mechanism to protect its host against foreign DNA. TtAgo bound with 5′-phosphorylated single-stranded DNA guide (13-25 nucleotides in length), effectively cleaved a foreign complementary DNA in vivo. Previously, we were among the pioneers who had utilized gene swamping experiments to demonstrate that evolutionarily conserved proteins, such as homeodomain-containing proteins, were not only conserved in structures, but also could functionally act in a similar fashion in a species that was diverged from a common ancestor over millions of years ago (Zhao J J, Lazzarini R A, Pick L. The mouse Hox-1.3 gene is functionally equivalent to the Drosophila Sex combs reduced gene. Genes Dev. 1993, 7: 343-354).

As shown herein the gene sequences of Natronobacterium gregoryi [NgAgo], Pyrococcus furiosus [PfAgo], Thermus thermophilus [TtAgo], Thermus thermophilus [TtAgo], and Methanocaldococcus jannaschii [MjAgo] were modified to that of SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4 correspondingly. These modifications resulted in enhanced expressions and/or activities of these human ANAGO in human cells. The human ANAGO described herein acts as a DNA directed gene editing nuclease in human cells.

The gene sequences of other microbial argonaute proteins, such as Clostridium butyricum [CbAgo], and Limnothrix rosea [LrAgo] may be also engineered in a similar fashion to generate species-specific ANAGO to eukaryotes for gene editing in eukaryotic cells, such as human cells.

The AISE technology described herein shall have at least following distinctive advantages over RNA-guided CRISPR/Cas approach:

1) The homology-directed repair or replacement (HDR) of AISE approach generally lead to measurable to high percentage of HDR editing event with superior precision, speed, and throughput, and without concerning about off-target effect. It is unlike the non-homologous end-joining (NHEJ)-mediated gene editing, which is error-prone and mainly utilized in CRISPR/Cas system.

2) A very versatile donor molecule, with either single-stranded or double-stranded, can be used in the ANAGO induced gene editing. The donor nucleic acid can accommodate as minimal as a single base change or as long as at least 1500 nucleotides of exogenous sequence. In fact, it has been reported recently that single-stranded oligodeoxynucleotides (ssODNs)-mediated knock-in of a donor fragment in mammalian cells occurs via HDR and is more efficient than using a double-stranded donor fragment.

3) ANAGO proteins are much smaller than a Cas nuclease. It is easy to fit into an adeno-associated viral (AAV) vector, a very promising tissue delivery system for clinical applications.

Unlike the CRISPR/Cas system, the precise genomic sequence editing using the AISE technology described herein has none or very low imprecise editing, since the AISE technology is mainly depended on homology directed recombination. The imprecise editing associated with AISE can be as low as about 0%, about 0.5%, about 1.3%, about 0%-6%, about 0%-5%, about 0%-0.1%, about 0.1%-6%, about 0.1%-5%, about 0.1%-4%, about 0.1%-3%, about 0.1%-2%, about 0.1%-1%, about 0%-1%, about 0%-2%, about 0%-3%, about 0%-4%, about 0%-0.5%, about 0.5%-1%, about 1%-1.5%, about 1.5%-2%, about 2%-2.5%, about 2.5%-3%, about 3%-3.5%, about 3.5%-4%, about 4%-4.5%, about 4.5%-5%, about 5%-5.5%, or about 5.5%-6% of the genomic PCR products, or any percentage in a range bounded by any of the above values. The AISE technology with very low or none imprecise editing provides a very powerful and desirable tool for precise genomic sequence editing, which enables wide applications using AISE to treat many gene associated diseases, disorders, or conditions, both known or yet to be known.

Furthermore, the AISE technology described herein has very low rate of the unintended indel events including both unintended deletion and unintended insertion at or around the target region, such as about 0%-2%, about 0%-0.1%, about 0.1%-2%, about 0%-1%, about 0.1%-1%, about 1%-2%, about 1%-1.5%, about 1.5%-2%, about 0%-0.1%, about 0%-0.5%, about 0.5-1%, about 0.1%, about 0.2%, about 0.3%, about 0.4%, about 0.5%, about 0.6%, about 0.7%, about 0.8%, about 0.9%, or about 1%, or any percentage in a range bounded by any of the above values.

The rate of the unintended sequence insertion event at or around the target region associated with AISE is very low, such as about 0%-2%, about 0%-0.1%, about 0.1%-2%, about 0%-1%, about 0.1%-1%, about 1%-2%, about 1%-1.5%, about 1.5%-2%, about 0.1%-2%, about 0.1%-1%, about 0.1%-0.5%, about 0.5%-1%, about 0.1%-0.3%, about 0.3%-0.5%, about 0.5%-0.7%, about 0.7%-0.9%, about 0.9%-1%, about 0.2%-0.4%, about 0.4%-0.6%, about 0.6-0.8%, about 0.8%-1.0%, about 0.1%, about 0.2%, about 0.25%, about 0.3%, about 0.4%, about 0.5%. about 0.55%, about 0.6%, about 0.7%, about 0.8%, about 0.9%, or about 1%, or any percentage in a range bounded by any of the above values.

The rate of the unintended sequence deletion event at or around the target region associated with AISE is very low, such as about 0%-2%, about 0%-0.1%, about 0.1%-2%, about 0%-1%, about 0.1%-1%, about 1%-2%, about 1%-1.5%, about 1.5%-2%, about 0.1%-2%, about 0.1%-1%, about 0.1%-0.5%, about 0.5%-1%, about 0.1%-0.3%, about 0.3%-0.5%, about 0.5%-0.7%, about 0.7%-0.9%, about 0.9%-1%, about 0.2%-0.4%, about 0.4%-0.6%, about 0.6-0.8%, about 0.8%-1.0%, about 0.1%, about 0.2%, about 0.25%, about 0.3%, about 0.4%, about 0.5%. about 0.55%, about 0.6%, about 0.7%, about 0.8%, about 0.9%, or about 1%, or any percentage in a range bounded by any of the above values.

The very low rate or none of unintended indel events associated with the AISE technology provides a very significant benefit in eliminating or significantly reduce the risks associated with the unintended indel events in gene therapy. Thus, AISE technology described herein could benefit a huge population of patients who have gene associated diseases, disorders, or conditions, both known or yet to be known.

The rate of the homologous directed replacement (HDR %) of the on-target integration of donor sequence detected with various methods using different human ANAGO are varied for different targets. The HDR % can be about 1%-100%, about 1%-95%, about 1%-90%, about 1%-80%, about 1%-70%, about 1%-60%, about 1-50%, about 1-5%, about 5-10%, about 10-15%, about 15-20%, about 20-30%, about 30-40%, about 40-50%, about 50-60%, about 2-4%, about 4-6%, about 6-8%, about 8-10%, about 10-20%, about 10-30%, about 30-50%, about 1%, about 3%, about 4%, about 4.2%, about 7.1%, about 10.3%, about 18%, about 19.5%, about 23.5%, about 32%, about 43%, at least 3%, at least 4%, at least 5%, at least 7%, at least 10%, at least 15%, at least 18%, at least 20%, at least 30%, or at least 40%, or any HDR % in a range bounded by any of the above values for the genomic PCR products of the cells transfected with various human ANAGO expression constructs. The fact that some embodiment using the AISE described herein has demonstrated 43% HDR of precise sequence editing indicating tremendous potential of AISE in gene therapy. The ability to manipulate any genomic sequence by AISE technology described herein may have far-reaching implications and opportunities in developing new treatments for many different human diseases and disorders. Some major applications contemplated herein are:

Cellular Immunotherapy

Cancer immunotherapy involves or uses components of the immune system such as antibodies and T cells to treat cancer patients. Recently, impressive treatment results have been reported in some cases of lymphoma, leukemia and melanoma with adoptive T-cell immunotherapy, in which autologous T cells are engineered to attack cancer antigen ex vivo and transferred back to the patient. The T-cell immunotherapy could be further enhanced via expressing synthetic receptors known as chimeric antigen receptors, or CARs, and knocking out the endogenous T-cell receptors with engineered nucleases such as the human ANAGO described herein. In addition, knocking out the human leukocyte antigen (HLA) via gene editing could avoid immune rejection of allogeneic cell therapy and offer a universal off-the-shelf cell therapy product.

Another useful application is to increase T-cell effector function and broadly enabling immunotherapy for diverse cancer types by knocking out genes of checkpoint inhibitor pathways such as CD274/PD-L1 (see the example 4 above) and CTLA-4.

Germline and Embryonic Engineering

Cystic fibrosis (CF) is a hereditary disease that affects the lungs and digestive system. The body produces thick and sticky mucus that can clog the lungs and obstruct the pancreas. Cystic fibrosis can be life-threatening, and people with the condition tend to have a shorter-than-normal life span. Cystic Fibrosis is caused by any one or combination of numerous mutations affecting the function of the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR). Currently, there is no cure for the disease, but the symptoms can be mitigated through therapy. Mutations can affect different parts of the pathway thereby leading to distinct natural history and calling for unique therapies. In all cases, gene-editing to correct the mutation before a child is born would greatly increase the quality of life of the future child. Under the responsible ethical guidance, the AISE technology would be a method of choice for gene-editing in these cases because it can work easily in germ cells or fertilized eggs, has minimal off-target effects, and can easily correct simple mutations via homologous recombination. For example, if a set of germ cells or fertilized eggs are sequenced in vitro and found to have the F508del mutation, the CFTR misfolding that would be expected to occur can be reverted to normal form by using ANAGO mediated precise gene-editing technology.

Optogenetics

Optogenetics is a research tool that is commonly found in neuroscience laboratories. In this context, the ability of Argonaute to swap out large loci such as mCherry (700 base pairs) can be fully taken advantage of. Mice in optogenetics experiments are bred to have a genetic cassette containing ion channels possessing a light sensitive property. Rhodopsins are generally used as the light sensitive segment. Viral vehicles are typically used to deliver the gene engineering tool to introduce the channel Rhodopsin, flanked by a promoter, to the cell types of interest. In this case, ANAGO in a form of RNA could be placed in the viral capsid and injected into the portion of the mouse brain that is under study. The genetic engineering can also be done upstream in the germline cells of an animal model, and application for which AISE technology would equally be well-suited. A probe with the capability of delivering targeted beams of light is then inserted into the animal brain (a probe containing an optic fiber, commonly). Once the rig is cemented in place, researchers can toggle the light between on and off and change the activity of the neurons in different settings, environments, and in the presence of novel stimuli. Thus, ANAGO mediated gene editing technology has the ability of accelerating discoveries in the realm of neuroscience.

Antiviral Therapy

Gene editing strategy has been used to remove the integrated viral DNA sequence from a host genome or knock out CCR5, a coreceptor used for primary HIV infection. Currently, several ongoing clinical trials are evaluating this approach in HIV-positive patients. Early study results provide promising proof-of-principle of a gene-editing approach in humans, which show safe engraftment and survival of CCR5-modified T cells and control of viral load in some patients. The ANAGO mediated gene-editing platform could also be applied to attack viral genomes of various DNA viruses such as HIV, hepatitis B virus, herpes simplex virus, and human papilloma virus etc. To circumvent the high mutability of viral targets, several donor molecules could be used simultaneously to target multiple critical sites in the viral genome.

Liver-Targeted Gene Editing

Liver is probably one of the most accessible organs for applying gene-editing technology to treat many different diseases. At one hand, the AISE technology could be used to correct mutations caused severe diseases including clotting disorders such hemophilia A and hemophilia B, as well as lysosomal storage disorders such as Fabry disease, Gaucher disease, Pompe disease, von Gierke disease, and Hurler and Hunter syndromes. On the other hand, the disruption of particular genes in the tissue may also have a beneficial effect. For example, reducing PCSK9 activity is correlated with decreased LDL level. In contrast to continuous administration of PCSK9 inhibitors, a liver-targeted PCSK9 knockout or variant substitutions could lead to long-lasting effect of lowering cholesterol levels.

Blindness Treatment

Another highly accessible organ for applying gene-editing technology is eye. Recent successes in clinical trials for the treatment of Leber Congenital Amaurosis type 2 (LCA2) have raised hope of using gene therapy to treat blindness caused by genetic mutations. LCA is the leading cause of childhood blindness and is caused by mutations in at least 18 different genes. Other autosomal dominant disorders such as forms of retinoblastoma, primary open angle glaucoma, retinitis pigmentosa and Fuchs endothelial corneal dystrophy, could potentially be treated by targeted editing of mutation sites. More importantly, the proven safety of adeno-associated virus (AAV) delivery in eyes and the compact size of the ANAGO system make it a particularly attractive gene-editing strategy in clinical settings.

Broadly speaking, with the advent of the ANAGO mediated precise gene editing technology, manipulating the genome of plants, animals, and particularly human pluripotent stem cells will become an attainable task, allowing to modify a genome with superior precision, speed, and throughput. AISE described herein will revolutionize our scientific communities worldwide for both developing experimental models to understand biological processes and strategies for improving wellness of living organisms.

In certain aspects, the de novo chemically synthesized single stranded oligodeoxynucleotide-mediated sequence replacement protocol described herein can be applied to any target site without addition of a guide molecule, thus simplifying genome engineering in living organisms.
